I was reading Hans Florine's description and condition of of Warren Harding and Dean Caldwell's 1970 "Wall of the Early Morning Light" (A3 5.8). His account of rivets that, "appeared as though they had been purposely chopped", fixed heads that "appeared to have been hammered on until on one very small dapple of wire was holding", and "rivets with the heads just sitting on their shafts as if someone had cut them off and just lightly glued or mashed the head back on" really has me wondering.

It's been almost 40 years since Royal Robbins attempted to "erase" the route but I had always assumed with such passage of time/traffic most of the chopped bolt would have been re-established.

My question(s): Is it possible that there are people still trying to erase the route? Is bolt chopping and removal of existing fixed gear all that common in the valley?
